Q: What does well-formed mean? A: It means the XML document follows basic syntax rules like correct nesting and having a single root element.
Q: Why is case sensitivity important? A: XML treats <User> and <user> as completely different elements, which can cause validation and parsing failures.
Q: Can I check specific XML formats? A: Yes, the validator checks general well-formedness which applies to all XML-based formats including RSS, SVG, and SOAP.
